Description of the Invention: [Technical Field of the Invention] The present invention relates to an electric power saving program that utilizes a program function such as a power saving method screen to save crying, and an idle processing that can be used for shoulders. Prior Art] In recent years, due to the increase in graphics in personal computers, the power consumption of the Μ Μ 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 The technology of power consumption. Traditionally, such VRAM power technology has been switched to a power saving mode via suspension or hibernation. 4 When switching to a power saving mode via suspending or hibernation, when the mode is restored from the power saving mode to a normal mode, the unconditional condition must be restored to the original stop before switching to the power saving mode. Therefore, 'the context of the VRAM is stored before the switching, and after restoring to the normal mode', the context is restored to the original condition before switching to the power saving mode according to the context of the health. However, if the power management is still supported by itself, when the VRAM is restored to the normal mode, 〇s will perform the initialization of the vram and the reproduction of the image data. Therefore, it is not required to store the vram context and restore it based on the stored data. In the case where the power management is not supported, such as Wind〇wsR (registered trademark) Ντ 4 〇, the storage and recovery of the VRAM context will be performed. In contrast, in the case of an OS support power management, such as WindowsR (registered trademark) XP/20〇〇/Me/98, which has one when the personal 1336436 computer stays for a predetermined period of time, the monitor power is turned off. The screen off timer function. If there is no wheeling from a keyboard or a mouse within a predetermined period of time, this function stops the display of an LCD panel or an external crt by a w-side such as APM (Advanced Power Tube). Save power consumption throughout the system. [Patent Document 1] Unexamined Patent Application No. 2 298 298 536 [Problems to be Solved by the Invention] According to the above prior art technique, when storing and restoring the vram context τ, an area for storage context is required and time. Especially when using hibernation technology, the VRAM context must be stored in a non-volatile memory like a hard disk. In recent years, the size of VRAM2 has been increasing, so the data transfer rate of the memory cannot be ignored. For example, in order to store the "VRAM context" on the hard disk, it will take more than thirty seconds. Since the VRAM cannot be used during the period, the processing conditions cannot be displayed. In the power saving mode with the -screen off timer, Even if the screen power supply does not have to be displayed, the power or clock supply of the VRAM: Considering the problems of the prior art techniques, one object of the present invention is: Even when an OS does not support power management, J. Or hibernation promotes a power saving mode, and does not need to store the recovery in the vRAM. Another purpose is: when the camp... and according to the data or the power supply of the VRAM, the data stored in the V content is not stored. According to the present invention, in order to achieve the above objects, an information processor according to the present invention is provided with a display memory for retaining image data displayed by the display device for cutting the display and the sound body. The drag, the bandit, and the hip are switched to a power saving state that causes the image data to disappear and the power saving of the memory from the power saving state a component; a storage area for holding a predetermined activation condition; a start-up condition of a predetermined routine when the start condition is satisfied; a routine termination member for terminating the routine; and When the routine terminates, the image data reproducing component that displays the 'Itn image (4) reproduction is executed; the information processor includes: when the display memory is switched to the power saving state or restored from the state, the memory area is rewritten to be stored. a startup condition rewriting component for starting the routine; and a startup condition restoration member that restores the rewrite activation condition to the original condition after the routine is started. A power saving method according to the present invention is an information processing Implemented in the apparatus, the information processor has: a normal-starting component that initiates a predetermined routine when a predetermined pre-determined starting condition is satisfied; a terminating terminating member for terminating the routine; and An image data reproducing component for reproducing image data of a display memory for retaining image data displayed by a display device; the method comprises The following steps: switching the display memory to a power saving state that causes the image data to disappear; restoring the display memory from the power saving state; rewriting the stored starting condition to switch the display memory to the power saving state or recover from the state The routine is started; the startup condition of the rewrite is restored to the original condition after the routine is started; and the routine of terminating the startup is completed. 1336436 An electric power saving program according to the present invention is an information processing of the present invention. „ — computer play Included according to the benefit of the mother XL · Execution contains = according to this ", or facilitates a computer in the configuration of the present invention, when each of the two steps: .... The power of the data disappears can not save. When switching to cause an image, it is necessary to display the original condition before the state is restored from the state.

L, . LA彳Μ ± This type must be accompanied by a process 'when the hanging is terminated ·- The reproduction of the image data of the memory is performed in order to restore the memory to the initial condition of the beginning of the routine. Furthermore, the routine is started when a predetermined starting condition is satisfied, and an input event is generated by the response. According to the present invention, the routine is initiated by rewriting the activation condition when the display memory is switched to or restored from the power saving state; when the display memory is restored from the power saving state, the termination is terminated. The normal condition; the activation condition is restored to the original condition, whereby the display memory is restored using the image data reproduction processing executed at the time of termination of the routine. When 0S does not support power management, the image data reproduction and initialization of the display memory is not performed when recovering from a power saving state. Therefore, the conventional 'display memory recovery is performed in a very time consuming manner', which saves the entire contents of the display memory before the display memory is switched to the power saving state, and is restored to the time when the power saving state is restored. Original condition. If the present invention is applied to this case, the display memory can be restored by the reproduction of the image data executed when the routine is terminated. Therefore, the time required to switch 1336436 to the power saving state and to recover from the state is greatly shortened. Conventionally, in a certain political situation, even when the display if device is switched to a power saving state and the display device does not have to receive the image data transmitted from the display memory, there is still no need to take any power saving measures for displaying the memory. If the present invention is applied to this case, when the display memory is switched to the power saving state, it is restored from the power saving state via the reproduction of the image data accompanying the routine termination. Therefore, it is easy to switch the display memory to the power saving state. Therefore, the display memory is usually referred to as a graphic memory or a video memory, i.e., a VRAM. The power saving state that causes the image data to disappear is like a state in which the power of the memory is stopped or the supply of the clock is controlled. Displaying 5 Replica. Image data reproduction means that each launched application performs display image data reproduction. When a memory is restored from a power saving state, the startup routine will be terminated. In this case, the routine can be terminated by generating a pseudo input event that terminates the normalization of the startup. Alternatively, after the display memory is restored from the power saving state, the routine is terminated in response to a job input from a keyboard or a mouse.

The activation of a display memory or the reproduction of image data can be performed by an OS installed in an information processor. A screen saver is used as a routine' and the start condition can be stored in a temporary storage area referenced by the 〇S. A time condition to specify the start timing can be used as a start condition. The time condition may be the lapse of a predetermined time period of 'a predetermined period of time', or a predetermined period of time in an idle state (no input state or no job state). In the case of Windows 11 (registered trademark) Ντ 4.0, there is a hardware cursor data in addition to the image data in the display memory, and the part must be initialized at the same time as the routine is terminated. [Embodiment] FIG. 1 shows a configuration of an information processor according to a first embodiment of the present invention. As shown in the figure, the information processor has a CPU (Central Processing Unit) for interpreting and executing a program, a main memory 2 for storing a startup program or data, for storing BI. 〇s, etc., a R 〇 M (read only memory) 3, a hard disk 4 for storing a program such as a 〇 (operation system), performing display according to data from the CPU 1 and using it as one a monitor 5 for interfacing the component, a VRAM (video RAM) 6 for retaining image data displayed on the monitor 5, for controlling the poor material transfer from the cpu i to 6 and according to the content of the VRAM 6 A graphic wafer 7 displayed on the monitor 5, a device 8 like a mouse and a keyboard, and a power controller 9 for controlling the power supply of each portion of the information processor. These portions are connected to each other via a bus bar 10. "Graphic wafer 7 is more 12". There is a function of controlling the clock supply and power supply of the VRAM 6. Γ 3/ has a power management function, and has an interface for the use of 0S. The m〇s are exemplified as a so-called APM (Southern Power Management) BI〇S. Wind.〆 (registered trademark) NT 4.0 does not support power management itself—(10) as (10). When (10) does not support power management, the information processor switches to suspend or hibernate (hereinafter referred to as a suspended state). Then, when recovering from this state, 〇S will not execute the required VRAJV [content recovery. However: 〇3 has a program called a camp saver. When a set state continues until the pre-start-id time The camp saver will be activated, which is stored in the temporary storage area when idle. The idle state means that there is no status from the job input such as the input device 8. This definition will consider whether to access the hard disk 4. After the screen saver is started, when the idle state is released by the job input, etc., the activity is stopped. Then, the application that is started by the startup program reproduces the image data of the VRAM 6 to restore the content displayed on the monitor to the screen saver. Original before starting Figure 2 shows a power management system of the information processor of Figure i. As shown in the figure, the system has a software interface as a hardware 21 81 〇 32 22, connected to the BIOS 22 and used to control power. A managed power management (pM) driver 23' is used to provide a software interface to execute a client driver 24 of the user's newly added hardware power management, and to rewrite the OS based on a topology from the PM driver 23. A temporary service area 25 pm service 26. The hardware 21 includes an input device 8 suitable for power management. For the hardware on the motherboard, the BIOS 22 will control the power management function, and the 91437 • 13-1336436 is not in the mother. The device on the board is supported by the client driver 24 software. The device not on the motherboard includes an external card or a PC card. The portion of the temporary storage area rewritten by the PM service 26 is used to set a screen saver. Part of an idle time before startup. Although the pM service 26 can rewrite the set period, the user can still set a start time when there is a keyboard or mouse input in a predetermined period of time. Screen saver. Figure 3 shows a process of switching to a suspended state in the power management system of Figure 2. Steps 31 through 38 of Figure 3 correspond to a message flow shown in Figure 2 to the CD. When the hardware .21 is switched to a suspension When a requirement of the state is set (step 31), the BIOS 22 notifies the PM driver 23 of the demand (step 32). The need to switch to a suspended state can be reduced by the hardware 2 1 by pressing a suspension button, The remaining battery capacity, closing-cover, etc. are generated. This requirement may be a demand generated by a program according to a user's _ indication. § When receiving a demand notification that is switched to a suspended state, the pM driver 23 Notify each customer to switch to a suspended state. The service 26 is first notified (step 33). When receiving this notification, the pM service 26 saves the value set as the idle time before the screen saver is started. The value is set in the temporary storage area 25, and instead of being set to one second, it is one. The smallest unit set (step 34). If an application or a device continues in the set state for the set time, then 〇3 will start the screen saver with reference to the value set as the idle time, so the screen saver will start after one second. After saving and rewriting the set value, the 'PM service 26 notifies the PM driver 23 VIII>.'. (Step 35). When the notification is received, the pM driver 23 notifies the other 1336436 clients 24 to switch to a suspended state (step 36). Upon receipt of this notification, each client driver 24 takes appropriate action, such as saving the information required when each corresponding device is restored from the suspended state. When each client is notified to switch to the suspended state, the PM driver 23 notifies each client 24, 26 of the BIOS 22:0S that it is ready to switch to the suspended state (step 37). Upon receiving this notification, the bios 22 can be used as a PS/2 keyboard, a PS/2 mouse, a USB device, etc., and access the hardware required for the suspension for one second. Then switch the system to the suspended state. The screen saver is activated after a set of idle time after the above rewriting, that is, after one second. Figure 4 shows a flow of information caused by a recovery from a suspended state. Fig. 5 shows a process performed when restoring from the suspended state. The procedure executed in steps 5 to 5 of Fig. 5 corresponds to the flow of information shown in Fig. 4 to Q). Recovering the required power supply based on a power button or a job of an input device, a job of a modem or a timer, etc. and the BIOS 22 recognizes that a request has been generated to recover from the suspended state (step 5 1 At the time, the BIOS 22 notifies the PM driver 23 of the need to restore from the suspended state (step 52). Upon receiving the notification of the recovery request, the PM driver 23 notifies each customer to recover from the suspended state. The PM driver 23 first notifies the PM service 26 to resume from the suspended state (step 53). When receiving this notification, the pm service 26 replaces the idle time before the start of a screen saver set in the temporary storage area with the saved set value, so as to convert the value back to the original set value before switching to the suspended state ( Step 54). The PM driver 23 then simultaneously notifies other clients to resume from the suspended state (step 55). Upon receipt of this notification, each client driver 24 saves the information based on the original condition according to 1336436. After restoring each corresponding device to switch to the suspended state, after notifying each client to recover from the suspended state, the PM driver 23 notifies each client of 22: 0S that it has recovered from the suspended state (step % received when received) At the time of this notification, BI〇s 22 generates a one-key input pseudo event from the hardware (step 57). According to the key input event, 〇s terminates the activity of the screen saver. 〇S guides each-starting program according to the use The image data reproduction of v RA m is performed by restoring the original function of the original display condition before the screen saver is started. This causes the VRAM content to be destroyed during the suspended state to be restored, and the display condition of the monitor is restored to be switched to the suspension. The original condition before the state. When 0S is Wind〇WSR (registered trademark) NT 4〇, VRam has 'hard-cursor data except for the image data, so it is necessary to initialize the part via a video driver. In an embodiment, the VRA_capacity is restored to the original condition before switching to a suspended state by using the image data reproducing function used when the screen saver is terminated, and thus, In the prior art technique of saving the VRAM inner valley and switching from the suspended state according to the saved data, the time required to switch to the suspended state or to recover from the state is greatly shortened. Show another system according to the present invention. Although it uses WindowsR (note that the hardware configuration of Figure 1 can also be applied to this system. Registered trademark) XP as 0S, as shown in Figure 6, this system has: Face BIOS 62, Used to plan a power management system trademark of a specific embodiment) 2000 or WindowsR (note for providing a 1336436-video mini-driver 63 as a monitor with the hardware 61 to enter a power saving mode for controlling The power management _pM driver 64, and the PM service 66 of a temporary storage area 65 that rewrites and restores 〇s according to a notification from the PM driver 64. Figure 7 shows the power supply being turned off in the power management system of Figure 6. A process that is used by a power manager to manage the appearance/disappearance of an input from a user and associated timers based on the user's settings to turn off the monitor power supply. During the set time period, when there is no input from a user, it is decided to turn off the monitor power supply (step, the video driver will be notified. The final decision is made.) Finally, a video mini-driver is called, and a video called by the drive is called. The BIOS or a flat panel shape is suitable as an ACPI BIOS control hardware for the graphics chip (step 72), and the planning monitor enters a power save mode (step 75). According to the present invention, the screen saver is tied to the planning monitor. The power save mode is initiated (step 73), and the video mini drive stops the clock supply or power supply via a VRAM of the graphics chip (step 74) to switch the VRAM to a power save state. In the process of step 73, similar to the specific embodiment shown in FIGS. 2 and 3 above, the interim time before the start of a screen saver set in the temporary storage area 65 is performed by the PM service 66 by the PM driver 64. Save 'and replace it with a value less than one second to enable the screen saver to start in one second. The reference number Q to Q) of Fig. 6 shows the generated information stream. In step 75, the video mini-driver 63 stops the video output via the graphics chip to the monitor. Furthermore, the transmission of the horizontally synchronized signal and the vertically synchronized signal is stopped, or the backlight is turned off. This causes the monitor to shut down. 1336436 Figure 8 shows a process (i.e., the d3 state described in the ACPI specification) that is restored to a conducting state after the monitor is switched to a closed state as shown above. The reference numerals Θ to G) in Fig. 9 show the generated information stream. When a keyboard or mouse operation causes an interruption, the system BIOS 62 is notified (step 8 1). At this point, the screen saver activity has not been terminated because the control has not been transferred to OS. § When the interrupt notification is received, the system B10 S 6 2 notifies the p Μ drive 6 4 that the monitor will be restored to the on state (step 82). The drive 64 notifies the service 66 and the video mini drive 63. When this notification is received, the service 66 replaces the idle time before the start of a screen saver set in the temporary storage area with the saved value (step 83). Upon receipt of the notification of the return to the on state, the video mini-driver 63 begins the clock supply or power supply via the VRAM of the graphics chip. It causes the VRAM to recover from the power saving state. Furthermore, the video mini-driver 63 starts the transmission of the video output supply to the monitor and the horizontal synchronization signal #vertical synchronization 彳s number, and the backlight is turned off (step 85) » it causes monitoring The device is restored to the on state. Then, when the user operates the input device, the screen saver will stop and reproduce the image data of the VRAM, and the monitor will again display the image displayed when the monitor is switched to the off state. According to the specific embodiment of the present invention, the content is restored to the original condition of switching to a power, ie, the order @刖, by using the image data reproducing function executed by the camp saver, so that the VRAM can be stopped when the monitor is turned off. Clock or power supply to achieve power savings. " 1336436 The present invention is not limited to the specific embodiment of the present invention, and can be implemented in a specific embodiment. For example, although in the above description, the saver is attached to Switch to -+ Ai Qin, power saving state is activated, but the screen saver can be started when the recovery from Christine ~ '#攸包力saving state. However, the situation is: when the cover y,,, Wo love When the screen is started, 〇S will store the resources stored in the VRAM to the main memory, then, 'Ye Baobei J will not expect this method, because during the recovery from the state of the state... The poor material of the child will disappear. If the cemetery is started when the power is restored, the unspoken content will be displayed on the screen for a while. Until the screen saver starts. [Advantages of the Invention] As described above, a conventional method according to the present invention is to activate the image data of the display memory when the 'starting condition' is satisfied when the activation condition is satisfied, and thus, the image data of the display memory is reproduced. This routine will be activated and Switching to the power saving state or rewriting the starting condition from the state to restore the starting condition to the original condition. Therefore, the display memory can be switched to a power saving state causing the content of the display memory to be damaged, or from The state is restored, there is no need to save and revert back to the display memory content. Therefore, even if the 0S itself does not support the power, the image is a suspension or a hibernation state. & - ^ 4 No. When a power saving state of the content of the memory is destroyed or restored from the state, the image data reproduction of the display memory is performed, and the switching can be easily performed to this - the power Saving state or recovering from this state. Furthermore, when the display device switches: like a power saving mode in a closed state, the clock or power supply of the memory can be displayed. Therefore, the power is further improved... 91437 19
